I had an etching service make the Tronic AMC and H-bridge boards for me but their minimum quantity was 5 on each of the boards. I soldered one of each up and I'm going to keep a pair for a spare but if anyone is in need of either I'd be willing to sell my extras. My cost on them was around $13 each/ $26 pair + shipping. If anyone is interested let me know.
Thanks!
